Yes, it looks like you are seeing the electrical noise and hum present in your house. Thing is, if the cable is shielded and properly grounded, you should not be seeing all that noise.
How do you have the shield connected? The inner conductor should connect to the red terminal, and the shield to the black. If the shield is not grounded and left floating, then you will pick up all sorts of hum and noise.
